Abstract
The utility model discloses a sealed shell, which comprises an upper cover and a lower cover. The upper cover comprises a top plate and an upper-cover side wall extending downwards from the peripheral edge of the top plate. The lower cover comprises a bottom plate and a lower-cover side wall extending upwards from the peripheral edge of the bottom plate. A first groove, which is surrounding the top surface of the lower-cover side wall, is arranged at the periphery of the top surface of the lower-cover side wall. The sealed shell is characterized in that at least one second groove is arranged at the periphery of the bottom surface of the upper-cover side wall. At least one third groove, which is surrounding the bottom surface of the first groove, is arranged at the periphery of the bottom surface of the first groove. The bottom of the upper-cover side wall extends into the first groove and is hermetically connected with the lower-cover side wall through a sealant filled in the first groove. Both the bottom surface of the upper-cover side wall and the grooved bottom surface at the top end of the lower-cover side wall are provided with grooves, so that the contact surface of the side walls with the sealant is increased. Meanwhile, liquids and the moisture in the air are prevented from entering the shell due to the multi-layer buffering effect of the grooves, so that circuit boards and electronic components in the shell are effectively prevented from being corroded by the liquids and the moisture.
Description
Technical field
The utility model relates to a kind of housing.
Background technology
Progress along with the modern development of auto industry and science and technology; need a large amount of to come various electrical and electronic parts and control device in the protection equipment with high-protection level, shock proof, corrosion resistant, fire-retardant nontoxic seal casinghousing, with guarantee equipment can be in various rugged environments and weather safety, work reliably.At present, most seal casinghousing adopts O-ring seal to seal in the design of hermetically-sealed construction, the shortcoming of this structure is: O-ring seal is the sealing function by playing after the upper and lower cover compression, need to consider gap between the upper and lower cover and the relations such as hardness of O-ring seal, and easily be subject to erosion, the corruption of external environment.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of good corrosion resistance, seal casinghousing that sealing reliability is high.
The technical scheme that the utility model adopts is: a kind of seal casinghousing, described seal casinghousing comprises loam cake and lower cover, loam cake comprises top board and by the loam cake sidewall of top board surrounding edge to downward-extension, lower cover comprises base plate and by the upwardly extending lower cover sidewall of base plate surrounding edge, periphery around lower cover sidewall end face is provided with a circle the first groove, be characterized in, periphery around loam cake sidewall bottom surface is provided with at least one second groove, and the periphery that centers on the first groove floor is provided with at least one the 3rd groove; The bottom of loam cake sidewall is stretched in the first groove, and is tightly connected by fluid sealant and the lower cover sidewall that is filled in the first groove.
Above-mentioned seal casinghousing, wherein, the periphery that centers on loam cake sidewall bottom surface is provided with together the second groove, and the periphery that centers on described the first groove floor is provided with twice the 3rd groove.
Above-mentioned seal casinghousing, wherein, the cross section of the bottom surface of the bottom surface of loam cake sidewall and the first groove all is wavy.
Above-mentioned seal casinghousing, wherein, fluid sealant is silica gel.
Above-mentioned seal casinghousing, wherein, seal casinghousing is the housing of automobile fan controller.
After adopting technique scheme, because the bottom surface of loam cake sidewall and the groove floor on lower cover sidewall top are equipped with groove, thereby increased the contact-making surface with fluid sealant, and liquid, moisture are entered enclosure interior played the multilayer cushioning effect, can effectively stop liquid, moisture to the corrosion of the circuit board in the housing, electronic devices and components.
Description of drawings
Fig. 1 is the partial cutaway schematic of an embodiment of seal casinghousing of the present utility model.
Fig. 2 is the overall schematic of an embodiment of seal casinghousing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is made and to further specify.
With reference to figure 1 and Fig. 2.Seal casinghousing according to an embodiment of the utility model comprises loam cake 1 and lower cover 2.Loam cake 1 comprises top board 11 and by the surrounding edge of the top board 11 loam cake sidewall 12 to downward-extension.Lower cover 2 comprises base plate 21 and by the upwardly extending lower cover sidewall 22 of the surrounding edge of base plate, periphery around lower cover sidewall 22 end faces is provided with a circle the first groove 23, periphery around loam cake sidewall 12 bottom surfaces is provided with at least one second groove 13, and the periphery that centers on the first groove 23 bottom surfaces is provided with at least one the 3rd groove 24.Among the embodiment shown in the figure, the periphery that centers on loam cake sidewall bottom surface is provided with together the second groove 13, and the periphery that centers on the first groove floor is provided with twice the 3rd groove 24.It is wavy that the cross section of the bottom surface of the bottom surface of loam cake sidewall and the first groove all is, and this wavy surface is comprised of the projection that mutually replaces and groove.
The bottom of loam cake sidewall 12 is stretched in the first groove 23, and is tightly connected with lower cover sidewall 22 by the fluid sealant 3 that is filled in the first groove 23.In one embodiment, fluid sealant can adopt silica gel.As shown in Figure 1, because the bottom surface of loam cake sidewall and the groove floor on lower cover sidewall top are equipped with groove, increase the contact-making surface with fluid sealant, and liquid, moisture are entered enclosure interior played the multilayer cushioning effect, thereby can between loam cake 1 and lower cover 2, realize good sealing.
To be connected more firmly in order making between loam cake 1 and the lower cover 2, also to be provided with a hasp 41 on the sidewall 12 of loam cake 1, be provided with the button pin 42 that is complementary with this hasp at the sidewall of lower cover 2, this hasp 41 interconnects with button pin 42.
Seal casinghousing of the present utility model can be used as the housing of automobile fan controller, and its degree of protection can reach IP69K.
